Editor crashes after quick toggling Static checkbox for the baked gameobject with LODs

Steps to repro:

1. Open attached project and 'LODProgressive' scene;
2. Open the Game view tab in the Editor;
3. While the lighting auto-bakes in the Hierarchy expand the House gameobject to see it's child gameobjects;
4. In the Hierarchy select 'House_1_lod_0' gameobject;
5. While baking in the Inspector quickly toggle and untoggle Static checkbox for the 'House_1_lod_0' gameobject;
6. Repeat step 4 several times (5-8 times).

Actual result:
Editor crashes after several toggle attempts. The crash stacktrace is empty. See attached video.

Expected result:
Editor doesn't crash after toggling static flags on the gameobject.

Notes:
- Reproduced on 2019.3.0a7, 2019.3.0a6, 2019.2.0b6, 2019.1.7f1, 2018.4.2f1;
- Reproducible on Windows and OSX.

The issue might not reproduce every time. If it doesn't try following:
1. Select 'House_1_lod_1' or 'House_1_lod_2' gameobject and try toggling static checkbox for them;
2. Change the rhythm of toggles, keep the pattern of 'quick toggle-untoggle-pause for 1-2 sec);
3. Select different gameobjects in the Hierarchy after toggling.
